Title: Linear solenoid and manufacture thereof
Inventor: MIKI NOBUAKI
IPC: H01F7/16
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and the size in the radial direction of a linear solenoid by winding a coil through an electrical insulation material layer made by coating an electrical insulation material on an outer peripheral wall of a core of a hollow cylindrical body which constitutes a part of a magnetic circuit and fitting a shaft inside the core slidably. SOLUTION: A linear solenoid consisting of a pressure adjusting valve part 1 and a thrust generation part 2 forms an electrical insulation material layer 241 by coating an electrical insulation material on an outer peripheral wall 212 of a core 21 of a hollow cylindrical body which constitutes a part of a magnetic circuit of the thrust generation part 2 and forms a coil 22 by winding a wire around the outer peripheral wall 212 of the core directly. Moreover, a lubrication material is coated on an inner peripheral wall of the core 21 to form a lubrication material layer 242, and a shaft 23 connected with a spool 11 of the pressure adjusting valve part 1 is fitted inside the core 21.  In this way, by winding the coil wire around the outer peripheral wall 212 of the core 21 directly, a conventional bobbin becomes unnecessary, and it is possible to reduce the number of parts and the size in the radial direction of the linear solenoid.

Title: Optical modulation device
Inventor: TOBA YOSHIKAZU
IPC: G02F1/01
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent a sensitivity from being lowered by connecting modulation electrodes of at least two optical modulators among optical modulators in series each other so that the same electric signals are impressed on them with the same phases to use single mode optical fibers without depending on the polarized plane of the outgoing light of a light siurce. SOLUTION: The AC voltage induced in a receiving antenna 33 passes through an impedance mudulating circuit 35 to be impressed on two optical modulators 41, 42 connected in series. The modulation electrodes of the two modulators 41, 42 are connected in series so that the same electric signals are impressed on them with the same phases. In this case, since coaxial cables of 50 Ωs are used in this device, the impedance of a closed circuit consisting of the modulation electrodes and the impedance modulating circuit becomes double and the voltage drip to be impressed on the modulation electrodes becomes half and the sensitivity is enhanced. Then, the light made incident on respective optical modulators 41, 42 is modulated by impression voltages impressed on the modulation electrodes and is emitted to be made incident on a photodetector 32.

Abstract: PURPOSE: To cause explosion to occur alternately in cylinders and contrive to economize fuel by a method wherein the dampers fitted in an intake passage are opened and closed by operating a switch at a driver's cab during running of an automobile.  
     CONSTITUTION: The damper (b) supported in the intake passage communicated to an intake port of the cylinder in such a manner that the damper (b) can be rotated about its axis to open and close the passage. For example, in a four-cylinder engine, when operating the cylinders in the order of 1-2-4-3, the dampers (b) corresponding to the cylinders #2, #3 are closed and the positions of the other dampers can be controlled by operating the switch at the driver's cab so that the cylinders #1, #4  can be operated alternately. The switch operation is conducted when the vehicle can  be driven by inertia, that is, when the vehicle is running on a flat road, a downward slop or the like, thereby economizing the fuel. A damper shaft (c) is hollow  and has a slit (e) at the lower side so that the outside air can be sucked in through  a filter (d) by the intake negative-pressure when the damper (b) is closed.

Title: Electric automobile
IPC: B60K17/04
Filed: 1992-03-19
Abstract: PURPOSE:To settle the slip rate of driving wheel stably within a reference level in a short time by providing a control means regulating a command signal, inputted through an input means, to a signal corresponding to a driving force obtained by subtracting a regulating driving force from an optimal driving force. CONSTITUTION:A controller 21 delivers command signals to four motor drivers 22 based on an output from an acceleration sensor 34 and rotates a motor 11 individually. Each tire speed is detected through a sensor 93 mounted on the shaft of the motor 11 and inputted to the controller 21 in order to determine the acceleration of tire based on the variation of tire speed. The controller 21 constantly updates the tire speed and stores an updated tire speed in a register and then determines an optimal driving force based on a driving force and an acceleration of tire at a selected past point of time. Furthermore, a regulating driving force corresponding to the tire speed and vehicle speed is determined and subtracted from the optimal driving force. According to the constitution the generated slip rate is settled below a reference level in a short time resulting in safety operation.

Filed: 1980-05-13
Abstract: PURPOSE:To sense the presence or absence of a main in the space to be detected without fail by memorizing the reflected wave of an ultrasonic wave when the man is absent, and comparing the wave with that when the man is present. CONSTITUTION:If the man 11 is absent in a cage 2, the reflections of the output signals B of a receiving element 4 become the reflectd waves X1 and X2 from hand rails 12 and a floor. The signals B are detected by a binary coding circuit 6, become binary coded output E, and are given to a memory device 7 and a comparator 8. While the output E of the binary coding circuit 6 is directly given to the comparator 8, and compared with the quantized time signal F (the signal stored when the man is absent) from the memory device 7 in the comparator 8. If both signals are coincided, the comparator 8 does not give the calculating input to a calculator 9. Therefore, the presence of absence of the man in the cage 2 can be sensed without fail.

Abstract: PURPOSE:To deposit a ceramic layer on a base material with high adhesiveness and to obtain a member having excellent wear resistance by using the plasma generated by electron cyclotron resonance to crack a gaseous raw material and depositing the ceramic layer on the surface of the base material. CONSTITUTION:About 2.45GHz microwaves are introduced from a waveguide 5 into a plasma forming chamber 2 and a coil 7 is energized to form about 875 Gauss magnetic field in the forming chamber 2. The electrons in the forming chamber 2 are, therefore, resonated and excited and the gaseous N4 or gaseous Ar or the like supplied into the forming chamber 2 through an introducing pipe 8 forms the plasma. The plasma is drawn out through a lead-out port 3 into the film forming chamber 1 as the magnetic field dissipates. The inside of the film forming chamber 1 is maintained under about 1X10<-4>-5X10<-3>Torr vacuum degree. The gas contg. the ceramics component introduced from an introducing port 9 is cracked by the plasma to induce the reaction. The ceramic film is thereby formed on the surface of the base material 10 in the film forming chamber 1.
